  hadrian/build-cabal.bat: fix build on Windows
  
  Commit 8cb99552f6 introduced a warning for a missing package index.
  However, the logic was faulty on Windows: the piping was broken, and
  "remote-repo-cache:" was being interpreted as a (malformed) drive letter,
  leading to the error:
  
    The filename, directory name, or volume label syntax is incorrect.
  
  This commit fixes that by using a temporary file instead of piping.
